Technical Field
[0001] This utility model relates to the field of wood shredder technology, specifically to a feeding mechanism for a forestry wood shredder. Background Technology
[0002] Wood shredders are equipment used in the forestry industry to crush branches and broken wood. The crushed branches and broken wood can be fermented quickly to make fertilizer, which can effectively shorten the fermentation cycle and reduce processing costs.
[0003] The existing crusher consists of a support frame, a crushing box, and a feeding port. When in use, the wood enters the crushing box through the feeding port for crushing. When crushing longer pieces of wood, one end of the wood is inside the crushing box, while the other end protrudes through the feeding port. However, due to the action of the crushing box, the protruding part of the wood gets stuck on the inner wall of the feeding port, causing feeding to become stuck. Workers need to manually push the wood to adjust its position so that it can be fed and crushed smoothly. When pushing, the wood is prone to breaking, which poses a certain safety hazard.
[0004] Therefore, in order to solve the above problems, a feeding mechanism for a forestry wood crusher is proposed. Utility Model Content
[0005] The purpose of this utility model is to provide a feeding mechanism for a forestry wood crusher, in order to solve the problem mentioned in the background art where the exposed part of the wood, under the action of the crushing box, gets stuck on the inner wall of the feeding port, causing feeding jams. Workers need to manually push the wood to adjust its position in order to feed and crush it smoothly. When pushing, the wood is prone to breakage, which poses certain safety hazards.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeding mechanism for a forestry wood shredder, comprising: a support frame, on which a shredding box is mounted, and a feeding port is mounted on the front of the shredding box; A pushing structure is installed on the feeding port. The pushing structure includes a fixed block, which is fixedly installed on the front of the feeding port. A rotating shaft is movably installed inside the fixed block through a bearing. Fixed rods are fixedly connected to both ends of the rotating shaft. A movable groove is opened at the bottom end of the fixed rod. A double-headed motor is fixedly installed on the front of the feeding port. A disc is fixedly connected to the output end of the double-headed motor. A guide post is fixedly welded to the surface of the disc. A rotating cylinder is movably installed at the upper end of the fixed rod through a bearing. The crushing box is equipped with a protective structure, which includes a fixed shaft. The fixed shaft is fixedly installed on the top surface of the crushing box, and a tilting plate is movably installed on the fixed shaft via a rotating shaft.
[0007] Preferably, the two sets of fixed rods are parallel to each other, and the rotation axis is located in the middle of the fixed rods.
[0008] Preferably, the guide post is located at the edge of the disk and is movably mounted inside the movable groove.
[0009] Preferably, the rotating cylinder is located at the upper front end of the feeding port.
[0010] Preferably, the flip plate is adapted to the feeding port.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model has a rotating cylinder set at the upper front of the feeding port. The rotating cylinder can swing back and forth under the drive of a double-headed motor, which can push the wood backward to loosen the wood and ensure the smooth feeding of the wood in the feeding port. No manual intervention is required, which ensures production safety.
[0012] 1. This utility model features a push structure that activates a dual-head motor, causing a disc to rotate. The disc then drives a guide column to rotate circumferentially. The guide column is movably mounted inside a movable slot. As the guide column rotates circumferentially, it drives a fixed rod to rotate around a rotating axis via the movable slot. The rotating axis rotates inside a fixed block, and the fixed rod causes the upper rotating cylinder to swing back and forth, feeding wood into the inner side of the feeding port. The bottom end of the wood extends into the crushing chamber for crushing, while the middle part of the wood adheres to the inside of the feeding port. Simultaneously, the top end of the wood protrudes from the inside of the feeding port. The swinging rotating cylinder pushes the wood backward, separating it from the inner wall of the feeding port. This facilitates stable feeding of the wood and prevents it from getting stuck inside the feeding port, requiring worker intervention. This ensures the safety and functionality of the device.
[0013] 2. This utility model has a protective structure. The flip plate is placed on the top surface of the feeding port to cover the feeding port and prevent rainwater and other debris from entering the crushing box, thus ensuring the stable operation of the crushing box. Pulling the flip plate will cause it to flip on the fixed shaft, which can open the feeding port. Attached Figure Description
